Description

 „... rttkLintoifflfIIHIIPMSHI ASSEMBLY ASSEMBLY

The utility model relates to light industry, namely to the nodes of the joints in the means of designing and modeling from soft elastic material, intended for the development of creative skills in children, and can also be used in the manufacture of various forms of packaging for various types of products and products.

Known connection node of at least parts containing two interacting connection elements, each of which is made on the corresponding parts, while one connection element has a hole and the other a protrusion (US 3811219 class. A 63 H 33/08, publ. 05.21.1974).

However, such a connection node, which is used in the designer, has limited technical capabilities and is dangerous for children, since the material used for their manufacture is hard and has sharp angles that cause various injuries during the game.

Known connection node of at least two parts, containing two interacting connection elements, each of which is made on the corresponding depgali, while one connection element has a hole and the other a protrusion made of flexible foam or foam rubber with an apparent density equal to 0.015 - 0.22 g / cm, for placement in a hole with interference (RU No. 17446 U1, 04/10/2001).

A disadvantage of the known joint is the limited technical capabilities due to the inability to connect thin-walled parts made of solid material.

The task to which this real utility model is directed is to develop a knot for connecting designer parts or packaging with advanced technical capabilities, allowing to form on its basis a wide range of spatial figures or models, both voluminous parts and thin-walled made of solid material, and while ensuring increased safety during its use and especially by young children during construction and subsequent games using assembled figures and modes oil.

Technical field

State of the art

The technical result is to ensure rigidity and reliability of the connection, allowing to maintain various loads from its own weight and the mass of objects in the package using such compounds, without changing the spatial shape of the assembled node, and also to ensure the repeatability of the assembly and disassembly processes.

Utility Model Essence

To achieve a technical result in solving the problem in the known connection node of at least two parts containing two interacting connection elements, each of which is made on the corresponding part, while one connection element has at least one hole, and the other at least one protrusion, the part with at least one hole made of thin-walled plastic or metal, or cellulose, and the hole has the shape of either a circle or a polygon or nogougolnika with at least one rounded corner, wherein the protrusion is formed in a single piece or a composite of at least two parts, and the opening area smaller than the cross sectional area protrusion.

These features are significant and interconnected causally with the formation of a set of essential features sufficient to achieve the specified technical result.

Short description drawing her

In FIG. 1 shows the connection node parts

in FIG. 2 - parts in the assembly process,

in FIG. 3 - a protrusion in the form of a polyhedron.

The utility model is illustrated by a specific implementation example, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving this set of features of a technical result. The connection node of at least two parts 1 and 2 (Fig. 1) contains two interacting connection elements, each of which is made on the corresponding part, while one connection element has at least one hole 3, and the other is at least one protrusion 4. In this case, the part with at least one hole 3 is made of thin-walled plastic or metal, or cellulose, and at least one protrusion 4 (Fig. 2) of the other part is made from elastic foam or foam rubber with an apparent density equal to 0.015 - 0.22 g / cm.

The hole 3 can be made not only in the form of a circle (Fig. 1,3), but also in the form of a polyhedron or polyhedron with at least one rounded edge.

Alternative embodiments of the protrusion 4 are proposed: in the form of one part (figure 2) or composite of at least two parts (figure 1), while the area of the hole 3, made either in the form of a circle or a polyhedron, is less than the cross-sectional area protrusion 4, made in the form of a polyhedron.

The difference between the areas of the hole 3 and the cross section of the protrusion 4 increases the reliability of the connection, and the flexibility of the elastic material from which the part with the protrusion 4 is made provides small efforts during assembly.

The connection elements with the protrusion 4 are made of flexible foam with an apparent density of 0.015-0.22 g / cm, which can be: polyurethane foam, polystyrene foam, polyvinyl chloride foam, polyolefins, foam or foam rubber with an apparent material density of 0.015 0.22 g / cm The use of the above foam materials in the parts of the designer and in other devices on the one hand eliminates the possibility of injury during assembly of the joint. And when used in designers, it eliminates the possibility of injuries during assembly and during the game with assembled models. On the other hand, the use of these materials in connection nodes expands technical capabilities by obtaining a wide range of compounds of various shapes using well-known cutting methods, which in turn allow the creation of models and packages of complex shapes, as close as possible to real-life objects.

The change in the apparent density of the elastic porous material in the direction of increase leads to an unreasonable increase in the consumption of material, difficulties in assembly in the manufacture of figures of complex construction and increased energy costs. The lower limit of the apparent density of the material is due to the impossibility of forming spatial figures, which should have a bearing capacity.

Utility Model Implementation Example

The utility model meets the criterion of industrial applicability, since its manufacture is possible using existing means of production using known technologies.
